The Red Sox placed Jacoby Ellsbury on the 15-day disabled list Saturday after the 28-year-old center fielder suffered a subluxation of his right shoulder in Friday's Opening Day romp over the Rays at Fenway Park.
The Sox would not say how long Ellsbury would be out, but this kind of an injury typically requires 6-8 weeks.
In a statement, the team said only, "We are in the process of gathering further information and determining the treatment plan.''
Manager Bobby Valentine said, "We'll try to get him back as soon as possible with the best possible care known to man. I haven't heard the word 'surgery' mentioned, but like I said, whatever the best possible care is, that's what he'll get.''
